Twitter All A-Flutter Over Possible Data Breach

"Twitter believes that your account may have been compromised by a website or service not associated with Twitter. We've reset your password ..."

So began an email making the rounds of Twitter users last week, as the microblogging website tried to get ahead of the curve on a possible data security breach. The company may or may not have come under a phishing attack Thursday. (They won't say.) In any case, just to be safe, management decided to send out the now-famous email to millions of Twitter users whose accounts "may have been compromised."

Or may not. Turns out, Twitter now believes "we unintentionally reset passwords of a larger number of accounts, beyond those that we believed to have been compromised."

Twitter apologized "for any inconvenience or confusion this may have caused."
